" 6 Claims. (01. 250-34 This invention-relates to X-ray apparatusand more particularly the invention contemplates an attachment'for radiographic apparatus whereby fluoroscopicwork' may be done, and thereafter --'radiographic work-may sun be done without necessitating removal of the attachment.

The object of the invention is, therefore, to provide suchan attachment which shall be simpie-in design and'operation yet which will ful- 'fill its purpose' efficie'ntl y. I More specifically; a furtherobject of the invention is to provide a subframe attachable to theframe of the'radiographic unit and carrying a panel and fluoroscopicscreen. The panel is movable onthesubframe between a position in which it is useful in the usualmanner in fluoros'copy, and a position in which is does not interfere with use "of. theapparatus in radiography; and'thej fluoroscopic screen'is also movable on the subframe whereby the same may be properly positioned relative to the X-ray tube Still a further object of the invention is to provide means for releasably connecting the the movements of these two parts may be synin connection with the accompanying drawing in which Fig. 1 is a perspective view showing a radi'ographic apparatus with our fluoroscopic attac hment applied' theretmthe parts being'in position for 'radiographic use; Figs. 2 and 3 are plan views largely diagrammatic illustrating the possible adjustments of the parts; and Fig. 4 is a detail sectional elevation showingthe manner of connecting the fluoroscopic screen with the X ray'tube mounting; 1 I

With reference now' tothe'drawing, 1 is a base supporting an upright'column 2'about which fits av sleeve 3 for rotational adjustment thereon. 4 ista carriage, vertically adjustable on the sleeve 3 but secured against r'otational movement relative thereto, and serving as a mounting for the usual X-ray tube means generally designated by the reference character 5. The mounting 4 and the parts carried thereby are preferably counterbalanced by a weight movable within a hollow in the column 2 and having connection with the mounting 4 as by the'chain 9 passing over a pulley 10. 6 likewise generally designates transformer means for serving the X-ray means 5 fluoroscopic screenwith the 'X-ray' tube whereby.

through a high tension aerial system including the conductors 7 and flexible leads 8, the transformer means being secured with the sleeve 3.

Thus the base 1 and column 2 comprise a frame for supporting the transformer means 6 and the X-ray means 5, the X-ray means being vertically adjustable on the frame, and the X-' ray means together with the transformer means being rotatably adjustable as a unit upon the frame.

' What has thus far been described comprises radiographic apparatus such as illustrated and described more in detail in the Patent No. L775,-

According'to our invention, we provide a bracket 11 adapted to be secured on the column 2 below the sleeve 3 as indicated, Fig. 1; whereby the bracket extends laterally of the column and in a vertical plane as shown. Mounted in the bracket 11 is'a vertical column 12, so that the columnlZ and bracket 11 comprise in a sense, a subframe adapted for attachment to the frame of the radiographic unit, this subframe serving as a frame for supporting'fluoroscopic means as follows.

, Vertically adjustable but non-rotatable on the column-12 is a carriage'13 which may be preferably counterbalanced by a weight movable in a hollow in the column 12 in a manner similar to the counterbalancing arrangement for the carriage 4 described. The carriage 13 supports an arm 14 adjustable about the vertical axis 15 and carrying a bracket 16 adjustable on the vertical axis 17 at the end of the arm 14. The bracket 16 has a pair of arms between which is mounted for adjustment about a horizontal axis,

a fluoroscopic screen 18;

Thus the fluoroscopic screen ls is bodily movplane toward and from the carriage 4. .The rod 19 carries at its end adjacent the carriage 4 a yoke 20 the crotchof which is adapted to fit about the neck portion 21 of the carriage 4 which extends laterally of the sleeve 3 to carry able vertically through the range of verticalad- I the X-ray tube means. Thus when the rod 19 is adjusted as shown Fig. 1,. the X-ray tube and the fluoroscopic screen are independently adjustable, but when the parts are in the posi- 5 tion indicated Fig. l, the screen will be maintained at the elevation of the X-ray tube regardless of vertical adjustment of the latter. On the column 12 are a pair of vertically spaced elbow brackets 22 fixed upon the column 12.

movement about the vertical axis extending therebetween. The outer arm positions of the brackets22 are long enough to'allow the panel 15 24 to swing thereagainst, and the panel has free swinging movement from such position. i

It will be apparent that, as indicated Fig. 2, where radiographic work only is to be done-the panel 24 and screen 18 may be swung clear of 20 then be employed as usual; whereas when fiuoro-; scopic work is to be done the parts may be positioned as indicated Fig. 3 so that a patient may stand against the panel. 24 and behindthe screen 18, with the X-ray tube behind the panel, and the screen 18 be caused to follow vertical adjustments of the X-ray tube means through the described connection had by the rod 19 and yoke 20.
